ORLANDO, Fla. — Tiger Woods finally brought the buzz back to the very thing that made him famous — winning.

Two weeks after another injury scare, and two days before his former coach’s book goes on sale, Woods looked dominant as ever Sunday in the Arnold Palmer Invitational.

It was his first PGA Tour victory since a sex scandal at the end of 2009 led to one of the greatest downfalls in sports. And with the Masters only two weeks away, Woods looks more capable of ever than resuming his pursuit of Jack Nicklaus in the majors.

Woods closed with a 2-under 70 for a five-shot win over Graeme McDowell.

The question two weeks ago was when he could play again. Now, it’s whether he can rule the sport like he once did.

■ Louisiana Open

BROUSSARD, La. — Casey Wittenberg won the Louisiana Open on Sunday for his first Nationwide Tour title, closing with a 6-under 65 for an eight-stroke victory.

The 27-year-old former Oklahoma State player opened with round of 66, 66 and 63 and finished at 24-under 260 at Le Triomphe Country Club. He earned $90,000.

CARLSBAD, Calif. — Top-ranked Yani Tseng won the Kia Classic on Sunday for her second straight LPGA Tour title and third in five events this year, closing with a 2-under 70 for a six-stroke victory.

The 23-year-old Taiwanese star became the second-youngest player to reach 15 LPGA Tour victories. Nancy Lopez was 22 when she reached the mark.

Tseng led wire-to-wire and finished at 14-under 274 on La Costa’s Legends Course.

Tseng won the LPGA Founders Cup last week in Phoenix and also won the LPGA Thailand in February. She led the tour last season with seven victories — including major victories in the LPGA Championship and Women’s British Open — and finished the year with 12 worldwide titles.

South Korea’s Sun Young Yoo had a 71 to finish second.

■ Miss. Gulf Resort Classic

SAUCIER, Miss. — Fred Couples made an 8-foot birdie putt on the final hole Sunday to win the Mississippi Gulf Resort Classic.

Couples started the day tied for the lead with Jeff Sluman, but moved ahead with a birdie on the first hole. He led the rest of the day until the 17th, when his bogey dropped him into a tie with Michael Allen.

But Couples was perfect on the 18th, which is the toughest-rated hole on the course. He hit his drive in the middle of the fairway and then stuck the approach 8 feet from the hole. His winning putt was slightly downhill and looked good all the way.

He shot a 3 under 69 in the final round to finish at 14 under.

■ Hassan II Trophy

AGADIR, Morocco — Matteo Manassero shot a 7-under 65 for a share of the third-round lead of the Hassan II Trophy on Sunday.

He joined Damien McGrane of Ireland (71) at 12 under, one stroke ahead of Jose Manuel Lara of Spain (70).

Manassero is keeping alive his hopes of making his professional debut at the Masters next month.

West Texas golfers

A number of golfers on the PGA Tour have West Texas ties. Here’s how they did at the Arnold Palmer Invitational in Orlando, Fla.

■ Sean O’Hair, Lubbock native: Finished tied for 29th and won $39,900 after shooting 69, 72, 70 and 77 to finish at even par.

■ Chad Campbell from Andrews: Finished tied for 42nd and won $20,400 after shooting 71, 76, 69 and 75 to finish three-over par.
